The streaming stick was recently purchased specifically so that we could stream Met Opera on Demand on our Samsung Smart TV coupled with a Vizio soundbar. There has been only a minor problem getting the Stick to pair with the remote. Otherwise, the system has behaved flawlessly and it has been an enormous pleasure viewing/hearing the library of Metropolitan Opera performances now available to me. A secondary bonus is the greater ease of accessing Netflix through Roku rather than through the Samsung system. I anticipate that this will also apply to the apparently greater choice of channels available on Roku.
Extremely easy to use and set up. however, there are many times the screen freezes. Too many resets. Really bummed when it is during the football games or good shows.
